Schuylkill River Trail

Schuylkill River Trail

Pennoni provided existing conditions plans for design of the Schuylkill River Trail portion which extends out into the Schuylkill River below Walnut Street and runs out in the River as a boardwalk for approximately 2,200 ft and ties back into land below the newly constructed South Street Bridge. GNSS horizontal and vertical control was established to relate this project to the Pennsylvania State Plane Coordinate System horizontally and to the North American Vertical Datum of 1988 (NAVD99) vertically. Soundings were originally provided by the U.S. Army Corps of Engineers, which were checked using a fathometer and GNSS positioning systems.
